RAILWAY-SWITCH.

Specification of Letters Patent.

Patented June 22, 1909.

Application led July 20, 1908. Serial No. 444,538.

To all whom it may concern:

Be it known that we, CHARLES W. Rm- NOEHL and MALCOLM W. LONG, citizensof the United States, said REINOEHL residing State of Pennsylvania, andsaid LONG residing at Harrisburg, Dauphin county, State of Pennsylvania,have invented certain new and useful mprovements in Railway-Switches, ofwhich the following is a full, scription, reference panying drawings.

Our invention relates to railroad switches, the object being to providea simple, durable, and eflicient means which may be set to maintain theswitch tongue of a railway switch yielding y in one of its twopositions, and automatically return it to such position after beingmoved therefrom; which may be clear, and exact debeing had to theaccomset to maintain the switch tongue yieldingly in its other position,and automatically return it to said other position after being movedtherefrom; and which may be set to maintain the switch tongueyieldingl)T in either of the two positions to which it may be adjusted.

The invention consists in the novel features of construction andcombinations of parts which we shall hereinafter fully describe andclaim.

In the drawings z-Figure 1 is a plan view of al railway switch sectionprovided with our invention. Fig. 2 is a vertical section, as on theline 2-2, of Fig. 5, including the cover for the casing. Fig. 3 is avertical section, as on the line 8-3 of `Eig. 5, including the cover forthe casing. Fig. 4' is a bottom view of the adjustable head for settingthe spring actuated mechanism. l? ig. 5 is a plan view of the box orcasing containing the spring actuated mechanism, showing the parts setin position to maintain the switch tongue yieldingly in one of its twopositions, and automatically return it to such position after beingmoved therefrom; the cover for the box being removed. Fig. 6 is a viewsimilar to Fig. 5, showing the parts set in position to maintain theswitch tongue yieldingly in the other position, and automatically returnit to said other position after being moved therefrom. Fig. 7 is a viewsimilar to Fig. 5, showing the parts set in position to maintain theswitch tongue yieldingly in either of the two positions to which itmaybe adjusted.

4 is a railway switch section, including the tongue 5, the heel end ofwhich is pivoted as at 6, and the side walls 7 and 8 between which thetongue 5 is arranged. 9 and 10 are the rails leading from the heel endof the switch, and 11, the rail leading from the point end of theswitch. The tongue 5 is movable laterally into engagement with eitherthe wall 7 or the wall 8; and when it is in engagement with the wall 7,car wheels are directed thereby between the rails 10 and 11, and when itis in engagement with the wall 8, car wheels are directed therebybctween the rails 9 and 11.

Secured to one side of the switch section 4, is a box or casing 12,provided with a suitable cover 13. Extending through a stufling box 14in the wall of the casing 12, is a rod 15, one end of which extendsthrough an opening in the switch section 4 below the switch tongue 5,and is secured to a lug 16 projecting downwardly from the switch tongue5. Theother end of the rod 15 within the casing 12 is screw-threaded,and screwed into a boss 17 on a plate 18 which extends over one end of aplate 19 resting upon the bottom of the casing 12. The plate 1S isprovided with a longitudinal slot 20, therein, through which extends apin 21, rising from the underlying plate 19.

The pin 21 projects above the top of the plate 1S and is provided with acollar 22 adapted to engage the top of the plate 18. A cotter pin 23extends through the collar 22 and pin 21, to hold the collar 22 in theposition just mentioned. The width of the end portions of the slot 2()is e ual to the diameter of the pin 21, and said wz s of the centerportion of the slot 2O are expanded, as at 24, to receive and lit thecollar 22, which may be adjusted into the expanded portion 24, for a pur)ose hereinafter explained.

Tie plate 19 is pivotally connected, as at 25, to one end of a lever 2G,which, is rotatably mounted on a pin 27 screwed into a boss on thebottom of the casing 12, and rising therefrom. The other end of thelever 26 is provided with a roller 28 which is engaged by a V-shaped cam29 projecting centrally from a bar 3() toward the pivot pin 27 of thelever 26. The lower ortion of the cam 29 is provided with a gui e-block31 arranged between two ribs 32 on the bottom of the casing 12 andforming a guide-way to direct the cam 29 toward and from the pinvpressure moving theswitch tongue 5 is -rethe head 38 to maintain thehead jgagement with vthe wall 8.

lto return the switch tongue;

V,abar

27 of the lever 26. The ends of the bar 30 are rovided withy ins33iwhichproject paralle to the guide-b ocks 31 and through-perforationsin lugs 34 on the casing 12. The projecting ends of the pins 33 are.provided with heads between which and the lugs 34 are finterposed.lsprings. 36 which encircle the ins 33 and force said pins and therewiththe bar 30 and the V-shaped cam 29 normally toward the pivot pin 27 ofthe lever 26.

Seated in a'depression 37 in the cover' 13, is a head 38 which isrotatably mounted on the' pin 27. -The upper endl of the pin 27 isprovided with a nut 39 :which engages a washer in the bottom ofa'depression 40 in 38 in position within the depression 37. The head 38'isprovided with a downwardly extending boss 41 the bottom of which isarranged just above the top of the lever-26.

YThe bottom of the boss 41 is provided with two teeth 42 which arearrangedin the same horizontal plane with and between two teeth 43projecting upwardly lfrom the top of the ever-26, whereby vthe head 38may be turned to. cause the teeth 42 to engage the teeth 43 =,and turnor adjust vthe lever 26 for a purpose hereinafter explained. The head 38is provided wi'th suitable radially-arranged slots 44 into'which anysuitable tool or bar may be inserted for the purpose of turning thehead38.

The operation is as followsz-VVh'en it is 'desired to` maintain theswitch tongue 5 vyieldingly against the wall 8,.and to automaticallyreturn itrto said position after being moved therefrom, the parts areset in the position shownin: Figs. 1,2, 3,-and' 5.

YIn this position of the parts, .the Y-shaped cam 29 is acting upon theroller 28 and lever 26 to' force the plate 19in a direction away fromthe switch section 4, thuscausing the pin-21 to engage one end of `the.slot-20 and act upon the plate 18 and rod 15 in a manner to draw theswitch tongue 5 over-into en- Should the switch tongue 5 be moved fromits position against the vwall 8, against the. action of the springs 36,the roller 28 will not pass over the point of the cam. 29 therefore,when'fthe moved, the eam29'will act upon 'the lever 26 to its positionagainst the-wall 8. When `it is 'desired to maintain the switch rtongue5 yieldingly in its otherposition, inengagement with the wall 7, and toautomatically return it to said other position after being movedtherefrom, or other suitable tool, isinserted in one of the slots 44inthe head 38, and the' head 38 is turned tocause the teeth 42 thereof to.engage Vthe teeth' 4310i `the'lever 26 and turn the l ever4 to move'its roller 28 `past the point of 'thefY-'shaped caml 29 against theaction of the springs 36, and Vinto engagel ment with the other side ofsaid cam, as l shown ,inyFig. 6. This adjustment ofi the leve1126 movesthe pin 21 through the slot 20 and into engagement with the other endthereof, and acts upon the plate 18 and therej with the rod 15, in amanner to force the switch tongue 5 over into engagementwith .the wall 7in which position it is held yieldingly by the action of the cam 29 andits connectons. Should the tongue 5 be moved against the action ofthesprings 36, the roller 28 will not pass over the point ofthe cam-29;therefore, when ,the pressure moving the switch tongue 5 is'removed, thecam29 will Fig. 5 and retain the switch tongue yielding] y I in,engagement with the walll 8,-this-may be `doneby inserting a bar orother tool Ain one of the slots 44 of the head 38,'and turning said headto adjust the-lever 26 to the position shown in Fig. 5. V] hen it isdesired to Vmaintain the switch tongue 5I yieldingly-in position againsteither the wall 7 or the wall 8 to whichit may be adjusted, 'the lever26 is adjusted. yupon the pin 27 to the position shown in Fig. 7, thusbringing the pin 21 to a position midway between the ends of the slot20; whereupon, the cotter pin 23 is removed from the collar 22 and pin21, and the collar 22 is dropped into the expanded central portion 24 ofthe slot 20. The cotter pin23 is then replaced within the opening inthe-pin 21, above the collar 22, to retain said collar in-'its positionwithin the expanded portion of the slot. Vtlhen the parts are in theposition shown in Fig. 7, the roller 28 is very near the point of theY-shaped cam 29, and the action of one side of the cam 29 is to forcethe switch tongue 5 yieldingly into engagement-with the wall 8. Shouldthe-switch tongue 5 be moved from its position in engagement with thewall 7, the roller 28 will pass over the point of the Y-shaped cam29,against the action of the springs-36 and the other side of the cam29will `then act upon ,the parts to hold vthe switch tongue 5yieldingly'in engagementwith the-wall 7. Thus, each time Vthe switchtonguel 5 ismoved from 'side to side, the roller=28 will move over thepoint of the cam.
